西安地铁2号线隧道通风系统设计

Tunnel Ventilation Design of Xi'an Metro Line 2

通过使用美国交通部SES软件,对西安地铁2号线隧道通风的优化方案设计进行建模计算。以地铁运行远期条件作为计算依据,对隧道内的温度、换气量进行统计分析,得出其隧道内温度在38℃以内、换气次数在7次/h以上能满足设计要求的结论,并对隧道内的压力进行计算,为其他设计提供数据参考。

By adopting the SES software of the Ministry of Communications of USA, a model was built and computation was carried out for the tunnel ventilation optimizing project design of Xi＇ an Metro Line 2. According to the long -term operation condition of metro, the temperature inside the tunnel and ventilation were analyzed statistically. Results indicated that the temperature inside the tunnel will be within 38 ℃ and the number of ventilations will be over 7 tines per hour, meeting the design requirements. The atmosphere pressure inside the tunnel was also calculated which can be taken for reference by other similar designs.
